Summarize Sound and
Introduction to Electromagnetic Waves
The unit we just finished revolved around the properties, behaviors and applications of mechanical waves, View this
video to see how pitch can be altered and remixed to form new sounds through mechanical wave interaction:

If you are not adventurous enough to mix sounds vocally you can experiment with the variables in this simulation to
"mix sounds" Sound Exploratorium OReflect on and summarize the concepts in the Mechanical Waves Unit while
